6 Claims.

The present invention relates to marking devices which are used in the manufacture of shoes to provide a shoe part, usually an upper blank, with marks useful as guides in subsequent oper- .5 ations such, for instance, as decorative stitching,

overlay locating and applying, and reinforce or underlay locating and applying.

There are at least two forms of stitching used in the shoe industry for decorative purposes. In

. 10 the first form, known as fancy stitching, the

stitches are inserted by a needle operating from and penetrating into the finished or grain face of the shoe part. In the second form, known as gimp stitching, a cord, or other filament, or narrow fabric, is secured to the finished or grain pings and appliques, the guide lines are marked on the finished or grain face of the shoe part. To locate the positions of the gimp stitching, the reinforces and the underlays, the guide lines are 25 marked on the unfinished or flesh face of the shoe part.

Heretofore attempts have been made to provide the shoe part with guide lines upon its opposite faces so that the marked shoe part could be 30 provided both with fancy and gimp stitchings,

or a. fancy stitch design correlated with a reinforce or an underlay, or a gimp stitch design correlated with a collar or other overlay. To provide the opposite faces of the shoe part with guide lines required two separate operations, in one of which the guide lines were marked upon the finished or grain face of the shoe part and in the other one of which the guide lines were marked upon the unfinished or flesh face of the 40 shoe part. While these two operations were performed in the same marking device it was neces sary touse two separate marking members, to

remove the shoe part from the device after it had been marked by one marking member, to remove 45 the marking member and replace it with the second marking member, to remove the shoe part and to reinsert it into the device in a position reversed from that it occupied during the first marking operation, in order for the shoe part to receive the marks of the second marking memher. As the shoe part is thin and limp it was found practically impossible to relocate its edge against the gage of the marking device for the second marking operation exactly as it was 10- 55 cated against the gage during the first marking operation. In consequence the marks were inaccurately placed on the shoe part by the second marking member, resulting in a lack of correlation between the fancy stitching and the gimp stitching, or between the fancy stitching and the 5 underlay, or between the gimp stitching and the overlay.

The principal object of the present invention is to produce a marking device by which the opposite faces of the shoe part may be provided with accurate, legible guide lines simultaneously.

To the accomplishment of this object, and such others as may appear hereinafter, the various features of the present invention consist in certain methods, devices, combinations and arrangements of parts hereinafter described and then pointed out broadly and in detail in the appended claims which possess advantages readily apparent to those skilled in the art.

The various features of the present invention will be readily understood from an inspection of the accompanying drawing, illustrating the best form of the invention at present known to the inventor, in which,

Figure 1 is a view in plan of the marking device;

Fig. 2 is a View in sectional elevation on the line 22, Fig. 1;

Fig. 4 is a detail view in plan of a marked shoe quarter, the grain face being exposed to view, and

Fig. 5 is a detail sectional elevation on the line 55, Fig. 1.

For the purposes of disclosure the various features of the present invention are illustrated herein as embodied in the improved Edwards Stitch Marker disclosedin the patent to Edwards, No. 1,796,686, March 17, 1931. Generally, the improved Edwards stitch marker is provided with a marking member which is transferred from a position where its marking edge is provided with a coat of ink to a position where the inked edge engages and marks one face of a shoepart supported by a gage removably mounted upon a bed. The marks made upon the shoe part by the marking member are used as guides in subsequent operations such, for instance, as fancy stitching, gimp stitching, overlay locating and applying, and reinforce or underlay locating and applying. To locate the positions of the fancy stitching and the overlays, such as collars, strip-- pings and appliques, the guide lines are marked on the finished or grain face of the shoe part. To locate the positions of the gimp stitching, the

reinforces and the underlays, the guide lines are marked on the unfinished or flesh face of the shoe part. I-Ieretofore, attempts have been made, through the use of the improved Edwards stitch marker, to mark the shoe part with guide lines upon its opposite faces so that the marked shoe part could be provided in subsequent operations both with fancy and gimp stitchings, or a fancy stitch design correlated with a reinforce or an underlay, or a gimp stitch design correlated with a collar or other overlay In preparing for these various markings by the improved Edwards stitch marker two marking members were made, one being provided with an edge for marking the finished or grain face of the shoe part, and the other being provided with an edge for marking the unfinished or flesh face of the shoe part. After the first marking member was inserted into the improved Edwards stitch marker it would be transferred from the ink pad to the finished or grain face of the shoe part supported on a gage of the bumper type carried by the bed. Then the first marking memher was removed, replaced by the second marking member, and the shoe part turned over and its edge relocated against the gage. Then the second marking member was operated to ink the guide lines on the unfinished or flesh face of the shoe part. 7

This mode of operation proved impracticable as it was found practically impossible to relocate the edge of the thin, flimsy shoe part against the gage for the second marking operation exactly as said edge was located against the gage during the first marking operation. In consequence the second marking operation was performed inaccurately.

In order to place the marks accurately upon the opposite faces of the shoe part and thus be able to correlate the fancy stitching and the gimp stitching, or the fancy stitching and the underlay, or the gimp stitching and the overlay, the finished or grain faces 6 (Fig. i) of the shoe parts 1, herein shown as a pair of quarters, are engaged with the transfer face 8 (Fig. 1) of a transfer sheet 9 which is supported, transfer face uppermost, upon the bed It. Mounted on the bed i8, over the transfer sheet 9, is the removable pattern plate ll provided with the cu outs l2 and l3 which receive the thin and flimsy quarters i. As shown in Fig. 1 certain portions of the walls of the cut-outs I 2 and 13 act as guides to engage the edges of the quarters and locate them properly to receive upontheir unfinished or fiesh faces i the guide lines inked thereon by the marking member I5.

The marking member 15 (Fig. 3) is provided with two sets of marking edges, one set making the marks on one quarter and the other set making the marks on the other quarter. Each set is provided with two edges l6 and H for marking the gimp stitch guide lines l8 and [9 (Fig. 1) and with two edges 20 and 2| for marking the overlay locating and applying guide lines 22 and 23 (Fig. 4).

With this construction pressure of the marking edges against the unfinished or fiesh faces of the supported quarters not only inks lines thereon but transfers from the transfer face of the transfer sheet identical lines to the finished or grain face of the supported quarters. Thus marking substance is deposited upon the opposite faces of the supported shoe parts simultaneously.

The guide lines l8 and [9 on the unfinished or flesh face of the quarters are used as guides in the subsequent gimp stitching operation. In this operation the needle operates from and penetrates into the unfinished or flesh face of the quarter in inserting the stitches which pass over and secure to the finished or grain face of the quarter a narrow strip of fabric, cord or other filament. Thus, the lines on the finished or grain face of the quarter corresponding to the guide lines l8 and I9 on the opposite face are covered and hidden from view by the gimp stitch- The lines 22 and 23 on the finished or grain face are used as guides in locating and attaching the strippings which are narrow bands having a width commensurate with the distance between adjacent marks 22 or 23 and a length corresponding to the lengths thereof. As the marks on the face I4 corresponding to the marks 22 and 23 are covered by the lining of the finished shoe they need not be removed.

By marking the opposite faces of the shoe part simultaneously the correlation of the gimp stitching and the strippings at their points of meeting (Fig. 4) on the finished or grain face of the shoe part is ensured.

The transfer sheet may extend from asupply roll 24 to a rewind roll 25. To this end the roll 24 is supported from brackets 26 (Fig. 1) projecting forwardly over the rear end of the pattern plate H. i To permit the unwinding of the transfer sheet, the roll receives at each end a head 27 (Fig. provided with a collar 28 abutting the roll. The heads 21 are formed on one end of pins 29 which are loosely fitted into the brackets 26. To insure that the transfer sheet is unwound eveniy from the roll 24 and to hold the roll 24 in position, coiled springs 30 are interposed between the brackets 26 and the collars 23, respectively. With this construction, the roll 24, although held securely in place, may be readily removed from the brackets 26 by pulling outwardly on the pins 29. As shown in Fig, 2, the transfer sheet upon being unwound from the roll 24 passes coated or transfer face up, under a shaft 3! journaled in ears depending from. the brackets 26. From under the shaft 3| the transfer sheet 9 passes along the surface of the bed is underneath the pattern plate H towards the front edge thereof. Here it is wound, coated or transfer face inward, upon a shaft 32 journaled in brackets 33 secured to the bed It! adjacent its front corners. One end of the shaft 32 is provided with a turning wheel 34.

While for purposes of disclosure the marks formed upon the opposite sides of the shoe part are to be used as guide lines in the subsequent operations of gimp stitching and of stripping locating and applying, it will be apparent to those skilled in the art that other marks may be made for use as guide lines in other subsequent operations such as fancy stitching and collar, reinforce and underlay locating and applying. That is, instead of correlating the guide lines employed in gimp stitching and stripping locating and applying, the illustrated embodiment of the present invention maybe used to correlate the guide lines used in gimp and fancy stitching, in gimp stitching and collar locating and applying, or in fancy stitching and reinforce or underlay locating and applying. It will be understood also that the finished or grain face must be engaged with the transfer face of the transfer sheet as the marking substance from the sheet may not be transferred to the unfinished or flesh face although this face will take the ink marks made by the marking member.

Nothing herein explained is to be interpreted as limiting the invention in the scope of its application to use in connection with the particular apparatus or the particular mode of operation or both selected for purposes of illustration and explanation. While the particulars of construction herein set forth are well suited to one mechanical form of the invention, it is not limited to these details of construction, nor to the conjoint use of all its features, nor is it to be understood that these particulars are essential since they may be variously modified within the skill of the artisan without departing from the true scope of the actual invention, characterizing features of which are set forth in the following claims by the intentional use of generic terms and expressions inclusive of various modifications.
